The Creation and Propagation of Radiation: Fields Inside and Outside of Sources
The Creation Propagation of Radiation Fields Inside Outside of Sources
2011/8/5
Abstract: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we ...
Holographic fermions in external magnetic fields
Holographic fermions external magnetic fields
2010/12/23
We study the Fermi level structure of 2+1-dimensional strongly interacting electron systems in external magnetic field using the AdS/CFT correspondence. The gravity dual of a finite density fermion s...
Jet deflection by very weak guide fields during magnetic reconnection
Jet deflection guide fields magnetic reconnection
2010/11/12
Simulations of antiparallel reconnection have shown collimated electron jets outflowing from the x-point, and associated highly elongated "outer electron diffusion regions." New PIC simulations with i...
Domain wall motion in ferromagnetic nanowires driven by arbitrary time-dependent fields: An exact result
Domain wall motion magnetic domain walls
2010/4/2
We address the dynamics of magnetic domain walls in ferromagnetic nanowires under the influence of external time-dependent magnetic fields. We report a new exact spatiotemporal solution of the Landau-...
Improved Faddeev-Jackiw quantization of the electromagnetic field and Lagrange multiplier fields
Faddeev-Jakiw method constraint quantization electromagnetic field Lagrange multiplier
2009/8/14
We use the improved Faddeev-Jackiw quantization method to quantize the electromagnetic field and its Lagrange multiplier fields. The method's comparison with the usual Faddeev-Jackiw method and the Di...

2010/10/18
We study the evolution of cosmological magnetic fields in FRW models with curved spatial sections and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechan...
In this work, we investigate the effects of torsion on electromagnetic fields. As a model spacetime, endowed with both curvature and torsion, we choose a generalization of the cosmic string, the cosmi...

2010/10/26
We present a detailed derivation of the effective dielectric constant to be used in the dispersion relation for electrostatic waves in the case of a plasma immersed in a inhomogeneous magnetic field, ...

An analytical solution to the Schrödinger equation for a multiple quantum well system subjected to an externally applied electric field the growth direction and an externally applied tilted magne...
Space Charge Limited Current at High Fields in Al-Ge-Al Surface Barrier Devices
Space Charg High Fields Al-Ge-Al Surface Barrier Devices
2010/4/15
The current-voltage (I-V) characteristics of Aluminium-Germanium-Aluminium (Al-Ge-Al) surface barrier devices at different fields (<1,000V/cm) have been investigated. The results reveal that in the lo...
